+# MEV Bot Project Organization Plan
+
+## 1. Documentation Organization
+
+### 1.1. Current State Analysis
+The documentation is currently well-structured with comprehensive coverage, but could benefit from better organization and categorization.
+
+### 1.2. Proposed Documentation Structure

+
+### 1.3. Documentation Migration Plan
+1. Create new directory structure
+2. Move existing documentation to appropriate categories
+3. Update cross-references and links
+4. Create new overview documents for each category
+5. Update main README.md with new documentation structure
+
+## 2. Logs Organization
+
+### 2.1. Current State Analysis
+Logs are currently in a flat structure with mixed file types and no rotation.
+
+### 2.2. Proposed Logs Structure
+
+```
+logs/
+├── app/                        # Application logs
+│   ├── mev_bot.log             # Main application log
+│   ├── mev_bot_errors.log      # Error-specific log
+│   └── mev_bot_performance.log # Performance metrics log
+├── transactions/               # Transaction-related logs
+│   ├── mev_bot_transactions.log # Transaction execution logs
+│   └── mev_bot_opportunities.log # Arbitrage opportunities log
+├── events/                     # Event processing logs
+│   ├── liquidity_events_*.jsonl # Liquidity events (rotated)
+│   └── swap_events_*.jsonl     # Swap events (rotated)
+├── archived/                   # Archived/compressed logs
+│   └── *.gz                    # Compressed old logs
+└── monitoring/                 # Monitoring and metrics
+    └── metrics_*.log           # Periodic metrics logs
+```
+
+### 2.3. Log Management Plan
+1. Create new directory structure
+2. Implement log rotation for event logs
+3. Set up compression for archived logs
+4. Configure retention policies
+5. Update application logging configuration
+
+## 3. Codebase Organization
+
+### 3.1. Current State Analysis
+The codebase follows a standard Go project structure with clear separation of concerns.
+
+### 3.2. Proposed Codebase Structure
+
+```
